Full Description 1. The effect of naturally occurring sunlight or light from artificial sources is excluded. Please refer to Note 2. When Test Methods D is cited, or otherwise referenced, a notation shall be included to this effect. Please refer to section 3. These accelerated ozone test methods may not give results which correlate with outdoor exposure tests or service performance.

A number in parentheses indicates the year of last reapproval. Scope 1. Intact specimens may be obtained from thin-walled sampling tubes, block samples, or clods. Speci- mens that are remolded by dynamic or static compaction procedures may also be measured by these methods.

It is common for the density unit weight of specimens after removal from sampling tubes and compaction molds to be less than the value based on tube or mold volumes, or of in-situ conditions. This is due to the specimen swelling after removal of lateral pressures.

The values stated in inch-pound units are approxi- mate. How one applies the results obtained using this standard is beyond its scope.

It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. Current edition approved March 15, Published April Terminology 3. Dry density measurements are also useful for determining degree of soil compaction. Since moisture content is variable, moist soil density provides little useful information except to estimate the weight of soil per unit volume, for example, pounds per cubic yard, at the time of sampling.

Since soil volume shrinks with drying of swelling soils, bulk density will vary with moisture content. Hence, the water content of the soil should be determined at the time of sampling. Dry density values are usually used in conjunction with compaction curve values Test Methods D and D N OTE 1—The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Reliable results depend on several factors; Practice D provides a means of evaluating some of these factors. Apparatus 5. A Class GP1 balance of 0. For methodA, the balance must be capable of measuring the mass Available online: www. This is usually accom- plished by a weighing hook built into the balance for that purpose, or a yoke assemblage is placed upon the pan which suspends a thin, non-absorbent string or wire, that is, a nylon line, etc.

N OTE 2—The waxes generally used are commercially available and have density values in the range of 0. A container heated by hot water, preferably thermostatically controlled, is satisfactory. The basket shall be constructed to prevent trapping air when it is submerged. A hairnet may also be used in lieu of the basket for smaller soil specimens. N OTE 3—Circumferential measuring tapes are recommended over cali- pers for measuring the diameter of cylindrical specimens.

Intact specimens may be obtained from thin-walled sampling tubes, block samples, or clods. Specimens that are remolded by dynamic or static compaction procedures may also be measured by these methods. These methods apply to soils that will retain their shape during the measurement process and may also apply to other materials such as soil-cement, soil-lime, soil-bentonite or solidified soil-bentonite-cement slurries. It is common for the density unit weight of specimens after removal from sampling tubes and compaction molds to be less than the value based on tube or mold volumes, or of in situ conditions. This is due to the specimen swelling after removal of lateral pressures. The values given in parentheses after SI units are provided for information only and are not considered standard.
